In my ontology creation . i have 2 class node and tier.  i have created instances node1.1, node2.1, node1.2 and node 2.2 and for tier tier1 and tier2.  i have created object properties and data properties.
in object property for example node1.2  hasUpstreamNode  node1.1. i wanted to assert a data property isUnique (boolean) for example <Node2.2 hasDownStream Node2,1> isUnique True. can anybody help me how to do it please.

i have pasted my code below.

from owlready2 import *
